Your home keys are the one thing you cannot fake your way past. When they’re lost, locked inside, or in the hands of someone who shouldn’t have them, it can be a nightmare.

Residential Locksmith Services for Every Door, Key, and Lock at Home
Apartment and House Lockouts
Lost keys, a slammed door, a key left inside – we open it without damage and get you back in, usually within the same hour. Call us any time you’re locked out.
Lock Rekeying After a Move
New place, old keys you can’t account for. Rekeying changes the pins so every old key stops working, for less than a full replacement. Call us the week you move in.
Lock Change and Replacement
When a lock is worn, broken, or just not secure enough, we swap it for new hardware matched to your door. Call us to replace a tired lock before it fails.
Deadbolt and High-Security Locks
A strong deadbolt is the cheapest real security upgrade there is. We install ANSI-grade deadbolts and high-security locks like Medeco and Mul-T-Lock, with keys no corner shop can copy. Call us to harden your front door.
Smart Locks and Keyless Entry
Stop hiding keys under the mat. We help you pick and install a smart lock that fits your door and building, set up codes and remote access, and show you exactly how it works. Call us to go keyless.
Broken Key Extraction and Lock Repair
A key snaps, a lock sticks, a latch stops catching. We pull the broken piece, fix the lock, and get the door working again. Call us before a sticky lock becomes a lockout.
Mailbox and Intercom Locks
Small locks, big hassle when they fail. We open, repair, and replace apartment mailbox locks so your mail stays yours. Call us for mailbox lockouts and swaps.
Home Safes
Safes jam, codes get lost, and old units wear out. We open, service, and install home safes so your valuables and documents stay protected. Call us for safe lockouts and installs.

24/7 Emergency Residential Locksmith - Get Back Into Your Home
We run an emergency commercial locksmith service across NYC with a fast response, day or night. Call us when you are locked out before a shift, when a gate jams, when a key breaks off in a storefront lock, or when a break-in leaves a door wide open. Our team sends a locksmith to your location in any of the five boroughs with the tools to open the door without wrecking it, then secures or upgrades it on the spot.
What we cover on every commercial call:
Locked Out of Your Apartment in NYC? Here’s What Happens When You Call
A lockout feels like an emergency, so the steps matter. When you call, we confirm the address, the door, and the lock type, then send the closest technician with the right tools. Most home doors open by picking or decoding, so the lock stays whole, and you’re back inside the same hour – no drilling on a lock that doesn’t need it. If your keys are gone for good, we rekey or replace the lock on the spot and hand you a fresh set.
Just moved in, or worried an ex or old roommate still has a copy? The same call covers it: we rekey or change the lock that day, so every key but yours stops working. For a forced door after a break-in, we secure the opening first, then fit a stronger lock so the next attempt meets a harder door.

Apartments, Co-ops, and Landlords - We Know the NYC Rules Most Locksmiths Skip
Changing a lock in a New York City apartment isn’t the same as changing one on a house. There are building rules, board requirements, and tenant rights in play, and getting them wrong can mean a fine, a fight with your landlord, or a job a co-op won’t let us finish. We work inside those rules, so the fix sticks.
A few things every NYC renter and owner should know:
Tell us the building and the situation, and we’ll fit the right lock the right way – for your door and your lease

Licensed, Insured, and Verifiable - The Home Locksmith You Can Check
The locksmith trade has a scam problem, and homes get hit with it most: a $29 phone quote that becomes $300 at the door, or a “tech” who drills a lock that never needed drilling. We don’t work that way. We follow the rules the city sets through the NYC Department of Consumer and Worker Protection, so the price, the work, and the receipt all match.
What stands behind every home job:
No hidden fees and no shortcuts. Call any hour for home lock work that follows every city rule.

Plenty of locksmiths will answer the phone. Not many show up fast, quote before they touch the lock, and actually know how NYC buildings work. We do all three, every time.
Stop scrolling through locksmiths. Call Alto Locksmith & Security for fast response, upfront pricing, and honest work on the door your home depends on.


Frequently Asked Questions
How much does a residential locksmith cost in NYC?
Cost depends on the job, the hardware, and the time of the call. As a guide, home lockouts run about $75 to $175, rekeying about $50 to $150 per lock, and deadbolt or high-security installs from $150 per lock and up. We confirm the price before any work starts, so no surprise bill waits at the door.
Can you rekey my locks instead of replacing them?
Yes, and it’s usually cheaper. Rekeying changes the internal pins so old keys stop working, while keeping your existing hardware. We’ll tell you honestly whether your locks are in good enough shape to rekey or whether replacement makes more sense.
I just moved into an apartment - should I change the locks?
We recommend rekeying or changing the lock the week you move in, since you can’t know how many old keys are out there. Most renters can do this, though your lease or building may ask you to give management a key, and we’ll help you stay compliant.
Can my landlord change my locks to lock me out?
No. Locking a tenant out without a court order is an illegal lockout in NYC. We won’t take a job that crosses that line, and we can rekey or change your lock only when you have the right to do so.
Is Alto a licensed locksmith in NYC?
Yes. We work under the rules of the NYC Department of Consumer and Worker Protection, and every job stays licensed and insured. Our license number is shown so you can verify it.
